A network administrator is completing an In-Service Software Upgrade (ISSU) for an
Intelligent Resilient Framework (IRF) virtual devices. The device has two members. Each
member has one management module. Member1 is currently the master. The administrator
has initiated a rollback time for this upgrade.
When should the administrator accept the upgrade?
A. After upgrading both members of the IRF virtual device
B. After checking the new software’s ISSU compatibility but before upgrading either
member
C. After upgrading member 1 but before switching over to and upgrading member 2
D. After upgrading and switching over to member 2 but before upgrading member 1
Answer: A
Explanation: Performing an ISSU for a multi-member IRF fabric
ISSU for a multi-member IRF fabric should be performed as per member in two steps: first
upgrade a subordinate member, and then upgrade the master and the other subordinate
members.

This HP 10500 Switch Series is receiving an average of 1 Gbps of HTTP traffic from
10.1.4.0/24. The switch starts to receive an additional 1 Gbps of HTTP traffic from
10.1.4.0/24. How does the switch handle the traffic?
A. It drops the traffic
B. It forwards the traffic but marks it yellow (for a higher drop precedence)
C. It forwards the traffic without remarking it in any way
D. It forwards the traffic but marks it for forwarding in a lower priority queue
Answer: C
Explanation:
Parameters
circommitted-information-rate: Specifies the committed information rate (CIR) in kbps.
cbscommitted-burst-size: Specifies the committed burst size (CBS) in bytes. The
committed-burst-sizeargument ranges from 4000 to 16000000, the default is 4000.
ebsexcess-burst-size: Specifies excess burst size (EBS) in bytes. Theexcess-burst-size
argument ranges from 0 to 16000000, the default is 4000.
pirpeak-information-rate: Specifies the peak information rate (PIR) in kbps.
greenaction: Specifies the action to be conducted for the traffic conforming to CIR. The
actionargument can be:
discard: Drops the packets.
pass: Forwards the packets.
remark-dscp-passnew-dscp: Marks the packets with a new DSCP precedence and
forwards them to their destinations. Thenew-dscpargument is in the range 0 to 63.
By default, packets conforming to CIR are forwarded.
redaction: Specifies the action to be conducted for the traffic conforms to neither CIR nor
PIR. Theactionargument can be:
discard: Drops the packets.
pass: Forwards the packets.
remark-dscp-passnew-dscp: Marks the packets with a new DSCP precedence and
forwards them to their destinations. Thenew-dscpargument is in the range 0 to 63.
By default, packets conforming to neither CIR nor PIR are dropped.
yellowaction: Specifies the action to be conducted for the traffic conforms to PIR but does
not conform to CIR. Theactionargument can be:
discard: Drops the packets.
pass: Forwards the packets.
remark-dscp-passnew-dscp: Marks the packets with a new DSCP precedence and
forwards them to their destinations. Thenew-dscpargument is in the range 0 to 63.
By default, packets conforming to PIR but not conforming to CIR are forwarded.

The network administrator is configuring Unidirectional Link Detection (UDLD) on trk1 on
an HP Provision witch. The trk1 link aggregation group has these settings:
Interfaces = 48 and 49
Untagged VLAN = 1
Tagged VLANs = 2-4
How should the administrator complete the setup?
A. Enable link-keepalive on both interfaces in the trunk (48 and 49).
B. Enable link-keepalive on interface 48, specifying the VLAN as 1.
C. On both interfaces in the trunk (48 and 49), enable link-keepalive, specifying the VLAN
as 1.
D. Enable link-keepalive on trk1
Answer: C
Explanation: * The following commands allow you to configure UDLD via the CLI.
Syntax: [no] interface <port-list> link-keepalive
Enables UDLD on a port or range of ports
* Ports enabled for UDLD exchange health-check packets once every five
seconds (the link-keepalive interval). If a port does not receive a health-check
packet from the port at the other end of the link within the keepalive interval,
the port waits for four more intervals. If the port still does not receive a healthcheck
packet after waiting for five intervals, the port concludes that the link
has failed and blocks the UDLD-enabled port.

A network administrator has begun configuring a Protocol Independent Multicast Sparse
Mode (PIM-SM) solution on all of the network infrastructure devices shown in the exhibit.
The administrator has selected the static method for configuring rendezvous (RPs) and
wants to use 4 as RP.
Where must the administrator configure the static RP setting?
A. On IRF 3 and IRF 4 only
B. On switch 1, IRF 2, IRF 3, and IRF 4
C. On IRF 2, IRF 3, and IRF 4 only
D. On IRF 2 and IRF 3 only
Answer: C
Explanation:
In Static-RP configuration, you need to configure “ip pim rp-address x.x.x.x” command on
every multicast enable router in your network including RP itself.

streams.
This is the configuration:
Some multicast receivers support IGMPv3.
Other receivers that need to stream support IGMPv2 only.
The multicast receivers' default routers enable IGMPv3 on the interfaces
associated with their subnets.
The routers are correctly configured to enable the IGMPv3 receivers to receive the
stream from the correct source
Which setting do the receivers' routers require to support the IGMPV2 devices?
A. An SSM policy that selects the IGMPv2 devices and binds them to an RP address
B. An SSM map that sets a rendezvous point (RP) for each multicast address
C. An SSM policy that selects the appropriate multicast destinations and binds them to an
RP address
D. An SSM map that sets the correct source for each multicast address
Answer: D
Explanation: IGMP SSM mapping
The IGMP SSM mapping feature provides SSM support for receiver hosts that are running
IGMPv1 or IGMPv2. This feature is implemented by configuring static IGMP SSM
mappings on the IGMP-enabled routers.
The SSM model assumes that the IGMP-enabled routers have identified the desired
multicast sources when receivers join multicast groups.
• A host running IGMPv3 can explicitly specify multicast source addresses in its reports.
• A host running IGMPv1 or IGMPv2, however, cannot specify multicast source addresses
in its reports. In this case, you must configure the IGMP SSM mapping feature to translate
the (*, G) information in the IGMPv1 or IGMPv2 reports into (G, INCLUDE, (S1, S2...))

Exhibit 2
In exhibit 1, all infrastructure devices are implementing OSPF on the interfaces. Exhibit 1
also shows settings for OSPF areas. Exhibit 2 shows some additional OSPF settings IRF 1.
The network administrator enters this command on IRF 4:
[ IRF4-ospf-1-area-0.0.0.2 ] abr-summary 10.2.0.0 16
The administrator verifies that the solution is functioning correctly. Indicate whether the link
state database (LSDB) on a device should include an LSA for 10.2.0.0/16.
